Helix Race GR chainrings are gravity optimized direct mount chainrings designed to withstand the punishment of downhill, bikepark, and freeride disciplines. They're crafted of AL-7075-T6, and highly CNC optimized for minimal weight penalty, and great looks. Paired with Helix Race GR Cranks, -7mm offset GR chainrings produce a 56.5mm chainline suitable for most long-travel bike geometries. Featuring e*thirteen's M4 narrow-wide tooth profile, they deliver improved chain retention, reduced noise and system wear, and seamless compatibility with both Shimano and SRAM drivetrains, (including T-type).Designed for use with Helix Race GR 83mm spindle cranksNot for use with Helix Race GR 73mm spindle cranks)56.5mm Chainline with Helix Race GR 83mm spindle cranksGravity optimized direct mount chainrings designed to pair perfectly with Helix Race GR cranks, and withstand the punishment of downhill and bike park-7mm offset for 56.5mm Chainline with Helix GR Crankse*thirteen Quick Connect Direct Mount for proven security and creak-free performanceDurable AL-7075-T6 construction for long wear-life, stiffness, and strengthM4 narrow-wide tooth profile provides excellent chain retention, reduced wear, and compatibility with Shimano and SRAM 11/12 drivetrains, including T-typeItem SpecificationsColorBlackDefined ColorBlackDirect Mount TypeDirect Mount e*ThirteenDrivetrain Speeds11Drivetrain Speeds12MaterialAluminumOffset7Round or OvalRoundTooth Count34Weight74 e*thirteen Helix Race GR Direct Mount Chainring Direct Mount Chainrings EAN: 4711280345243
